ok well im new to hondata...

I have a stock LS block
pr3 head with a PnP, oversized valves, and stock b16 cams
440cc injectors
now my question is...
Can I take a stock map and change it to 440cc injectors in the Fuel Trim section and run correctly? Or do I have to change everything over...also what would be a good map to start with? P72, P30, ITR,P61....?

TIA
Darren

You will have to properly tune the fuel to get the right air fuel ratios using a wideband.

but will just changing the injectors from 240 to 440 will the car atleast start up or will i have to basically start from scratch? because of how much bigger the injectors are.

You can recalibrate it for the correct injector size. It should start up.

The point he is trying to make is that you can't assume it is safe / good... You need to retune as everything is merely a basemap for a motor, each one will require different values.
